If you don't remember your password, you'll need to reset it to access your account. Depending on the way your account is set up, you may see a Forgot your password? or similar link on the change password page. If so, use that link to get help resetting your password. If you can't reset your password this way, contact your helpdesk.

Why can’t I connect to my account from my mobile device or desktop e-mail program after resetting or changing my password?

You need to update the password value in the settings on your mobile device or desktop e-mail program (for example, Apple Mail, Mozilla Thunderbird, Microsoft Outlook, or Windows Live Mail) each time your password changes.

To resolve this, make sure that the password entered on your mobile device settings or desktop e-mail program settings matches the most current password that you use to sign in to Outlook Web App. For more information, see Change Your Account Password.

You need to sign in to your account in Outlook Web App the first time you access it. If you successfully signed in the first time but can't sign in later, try doing one of the following:

Use the full e-mail address with the domain name (example: tony@contoso.com) when you sign in to your account.

Make sure you're using the correct sign-in name. Your sign-in name may be just your user name (for example, Tony), or it may be your full e-mail address (for example, tony@contoso.com). Your administrator should give you this account information after your account is created.

If you know you're using the correct Windows Live ID but still can't sign in, you may have already signed in to another service using a different Windows Live ID account.

Sign out of any applications, such as Windows Live Messenger, that you've signed in to using a Windows Live account other than the account you're using to sign in to get to your e-mail. Then sign in to your account again. For information about how to determine the Web address you should use to sign in to your account, visit How to Sign In to Outlook Web App.

Why am I asked for profile information when I sign in to my account in Outlook Web App?

The first time you sign in to your e-mail in Outlook Web App, you may be prompted to fill in your profile information. If your account was created before October 25, 2007, you may be prompted to fill in your profile information again. After you've filled in the profile information and accepted the Windows Live service agreement and Privacy Statement, you won't be prompted for this information again, and you should be able to sign in and use the account as you ordinarily would.
